The assemhlyis such that ordinarily no adjustments to make except when a different type of button is being used, members 16 may require a slight adjustment by operation of the screw and slot arrangements. Otherwise, the device without any adjustment is capable of operating with various sizes and shapes of shank buttons. This device is highly desirable for use with high speed machines where the time element for introducing buttons and removing the sewed product consumed many times the time necessary for sewing operation. Therefore, a considerable advantage in the present invention lies in the much greater speed of introduction of buttons into the sewing operations. Furthermore, the device is strong and sturdy and has been found by ample tests to withstand the severe services necessary in machines operating at as high as 3600 revolutions per minute;

Although I have described my inventionfsetting forth a single embodiment thereof, it will be apparent to those skilledin the art that various changes in the details of construction may be 'madein the invention within the scope thereof,

Various changesin the means'for 'attachingthe device to a-sewing machine may be provided'an'd the formand arrangement-of parts may be varied at will. Therefore, the invention is to be broadly construed and'not to be limited except'by the character of the claims appended hereto.

What I claim is: g 1. A shank button holder for sewing machines comprising a base member adapted to be secured to a sewing machine, a substantially horizontal rigid extension thereon terminating in a rigid fixed-jaw, a second'rigid jaw cooperating theree withand pivotedto said extension, means for biasing said second jaw toward said first jaw, the adjacent sides of said jaws normally'contacting under the action of said biasing means and having cooperating means for receiving the shank of a button for-passage of a needle therethrough between the jaws when'sep arated by said shank.

2. A shank button holder for sewingmachines comprising a base member adapted to besecured to asewing machine, a substantially horizontal rigid extension thereon terminating in a -rigid fixed jaw, 'a second rigid jaw cooperating there with and pivoted to said extension, means'ffor biasing said secondjaw toward saidfirst jaw, the adjacent sides ofsaid jaws normally con tacting under the action of saidfbiasing means and havingbooperating means for-receiving the shank of a button for: passage of a'needle therethr'ough'between the jaws when separated by said' shank, and means on each of said jaws adapted to contact with'that side of a shank button adjacent to its shank to prevent movement thereof during sewing.

3. A shank button holder for sewing machines comprising a base member adapted to be secured to a sewing machine, a substantially horizontal rigid extension thereon terminating in a rigid fixed jaw, a second rigid jaw cooperating therewith and pivoted to said extension, means for biasing said second jaw toward said first jaw, the adjacent sides of said jaws normally contacting'tunder the action 'of said biasing means and having cooperating means for receiving the shank of a button for passage of a needle therethrough between the jaws when separated by said shank, and means on each of said jaws adapted to contact with that side of a shank button adjacent to its shank to prevent movement thereof during sewing and including fingers extending upwardly at the outer ends of said jaws.

4. A shankwbutton holder for sewing machines comprising a base member adapted to be secured to a sewing'm'achin'e, a substantially horizontal rigid extensionxthereon terminating in a rigid fixed law, a second rigid jaw cooperating'therewithand pivoted to saidextension, means for biasing said second jawtoward-"said first-jaw; the adjacent sides of said jaws normally contacting underthejaction of said biasing means and having cooperating means for receiving the shank of a button forpassage of a needle therethrough between-'the jaws when separated by said shank, and means on each of 'said jaws adapted to contact with that side of a shank button adjacent :to its'shanl'c to prevent movement thereof during sewing and including fingers extending upwardly at the outer ends or said jaws, and means for adjusting theposition of said'fingers on said'j'aws.
